Abstract (en)

[origin: WO2015022025A1] The present invention relates to a process for the introduction of liquid feeds to a polymerisation process, and in particular provides a process for the introduction of a fresh feed selected from fresh comonomer and fresh inert hydrocarbon to a polymerisation reactor, which polymerisation reactor is part of a polymerisation process comprising high and low pressure recovery systems, said high pressure recovery system being at a pressure of 0.5 MPa or above and said low pressure recovery system being at a pressure of less than 0.5 MPa, which process comprises passing said fresh feed and a process stream comprising a first component selected from hydrogen, nitrogen and methane and a second component which is a monomer to a separator which is part of the low pressure recovery system and is at a pressure of 0.4 MPa or less to produce a first stream comprising the majority of the first component and a second stream comprising the second component and the majority of the fresh feed, and passing the second stream to the polymerisation reactor.
